What's New?

Is it New Bike Time? Of course!
It's pretty obvious this is when people are out on the roads & trails having fun on their new bikes. This is a great time for a new bike because you've got 3 months of great riding weather ahead of you! Chain Reaction features the very best bikes from Trek & Electra, as well as the highest-quality travel bikes from Bike Friday. Road, Mountain, Hybrid, Electric assist, Kids... we've got them all. Probably the best selection in a single location you'll find anywhere on the peninsula too.
Got a bike that needs repairs?
We can handle that! If you purchased your bike from us, remember that you can bring it in anytime, without calling ahead, for minor on-the-spot adjustments of brakes, gears and wheels (at no charge; this is included with any bike purchased from us). For flat tires, again, no appointment needed. Where possible we try and do flat tires while you wait, but there will be times that's not possible. At most you will be leaving your bike overnight. For normal (bigger) repairs, calling ahead to schedule an appointment makes sense because, at this time of year, our repair backlog can grow quickly! It's normal for better bike shops to need 5 to 10 days. Better shops will not put speed in front of quality.
It's E-Bike time at Chain Reaction! E-Bikes are the latest thing; find out why! Commute to the office without needing a shower, bring home the groceries (even if you live on top of a hill!) or keep up with your obsessive-cyclist partner. Prices start at just $1299 (Oyama folding E-bike) up to the incredible Trek Super Commuter 8 at $5199.
